WATER-MOTOR.

Specification of Letters Patent.

Application filed August 19, 1912.

Patented Dec. 23,1913.

Serial No. 715,725.

To all whom it may concern Be it known that I, IsiDoR YASSENOFF, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Water-Motors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in reciprocating water-motors of the type adapted for operating washing machines. The object of the invention is to provide a water-motor, simple in construction, durable and eflicient in operation, and possessing the features and functions hereinafter described and claimed.

Another object of the invention is to provide means for supporting the piston leathers when the same have become dried out. And still another object of the invention is to provide improved means for adjustably mounting the cylinder of the motor. Other objects of the invention will be described in the specification and particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a side elevation of the motor partially in section; Fig. 2 is a section on the line 17-?) of Fig. 3; Fig. 3 is a section on the line aa of Fig. 2; Fig. 4 is a section on the line cZcZ of Fig. 3; Fig. 5 is a section on the line 6-6 of Fig. 3; Fig. 6 is a section on the line 0-0 of Fig. 3; and Fig. 7 is a section on the line f-f of Fig. 1.

Throughout the specification and drawings, similar reference characters indicate corresponding parts.

Referring more particularly to the drawings 1 represents a cylinder containing a piston 2. The piston 2 is attached to a hollow piston rod or pipe 3 which extends out of the cylinder through a boss 4 and a stuffing gland 5 and transmits the power generated by the motor. The end of the piston rod 3, opposite the piston, is attached to a rack 6 in mesh with a pinion 7 on the upper end of a vertical shaft 8. The shaft 8 supports the dasher (not shown) of a washing machine and will be again referred to. The other end of the cylinder is provided with a separate head 9 having an inlet chamber 10 and an exhaust chamber 11 for the motor fluid. Attached to the head 9 is a cap 12 provided with screw threaded apertured bosses 13. To one of these the end of inlet hose is attached and to the other the exhaust hose is attached. The apertures in the said bosses lead to the inlet and exhaust chambers 10 and 11 respectively as is shown in Fig. 3. Mounted in the inlet chamber 10 is a double puppet inlet valve l and in the exhaust chamber 11 is placed a double puppet exhaust valve 15. The said valves, on one side of the head 9, communicate directly with the interior of the cylinder and on one side of the piston, and with the cylinder on the other side of the piston through a channel 16 and a chamber 17 in the cap 12. When the valves are in the position shown in Fig. 3, the inlet or live fluid is passing through the chamber 10, past the valve 14 and into the chamber 17 through the channel 16, and into the cylinder, where it expends its energy in moving the piston in the direction .of the arrow. Meanwhile, the exhaust fluid onthe opposite side of the piston is passing the valve 15 through the exhaust chamber 11. When the piston reaches the end of its stroke, the said valves lt and 15 will be shifted, thus permitting the live fluid to pass directly into the cylinders, and the exhaust fluid to pass through the channel 16 and the chamber 17 The valves are shifted by the following means: The said valves are provided with stems 18 which are connected by a yoke 19 held upon said stems by cotter pins 20. Coupled to the yoke 19 is a rod 21 which extends into the hollow piston rod 3 and is provided with a head 22. Extending from the piston 2 are cars or projections 23 upon which a buffer or cup 2 is loosely mounted. The movement of said buffer 24: in one direction is arrested by the piston and in the other by cotter pins 25 which normally maintain it upon the projections 23. The buffer 24 is adapted to engage the yoke 19. Mounted between the said buffer and the piston 2 is a conical spring 26 which is adapted to be engaged by the head 22 of the rod 21.

When the piston 2 is moving in the direction of the arrow, Fig. 3, the buffer 24: will engage the boss of the yoke 19, and as the pressure of the live fluid in the chambers 10 and 17 will hold the valves upon their seats, the spring 26 will be compressed. lVhen the piston is moving in the opposite direction and the valves are shifted to their seats opposite those shown in F 3, the pressure of the live fluid in the chamber 10 and cylinder will hold the valves on their seats and the spring 26 will be compressed by the head 22. lVhen the piston reaches the end of either stroke, the combined action of the moving piston and the compressed spring will shift the valves, thereby reversing the travel of the piston. By thus constructing a motor, the various parts may be made of sutlicient strength to secure durability, and as the motor is of simple construction, the same will work at high efficiency.

The piston 2 is provided with leather cups or packing 27. Such packing is subject to dry out when the motor is out of use for a time. To prevent said leathers or packing 27 curling away from the inner wall of the cylinder, when they become dry, a series of teeth 28 are provided which lie under the circumferential edges of the packing. The said teeth 28 hold the leathers against the surrounding cylinder walls and thus permit the water to gain access to the packing to saturate the same when the motor is again in use.

The motor is supported by the following adjustable device, which is a very useful feature. The boss l is adapted to receive a nut 29, and lies between two projections 30 which extend from a base member 31 mounted on the lid 32 of the washing machine. (See Figs. 1 and 7). The space between the projections 30 is of greater width than the diameter of the boss l. This permits the motor cylinder to be moved vertically or laterally to secure the proper mesh between the rack 6 and pinion 7. hen the cylinder is in its proper position, it is held rigidly in such position by the nut 29 which clamps the projections 30 between said nut and the ad jacent end or head of the cylinder. Extending from the lower side of the base 31 is a boss 33 which extends through the lid 32 and forms a bearing for the shaft 8. The boss 33 is provided with an inner annular recess 34 which receives absorbent packing 35 such as felt. This packing is adapted to absorb any oil or grease which may run out of the bearing, thereby preventing the clothes in the tub becoming soiled.

Having described my invention, I claim,

1. In a water motor, a cylinder having a head provided with inlet and exhaust chambers, a piston in said cylinder, a tubular piston rod attached to said piston and extending out of the cylinder, inlet and outlet valves in said chambers, a yoke connecting said valves, a cup slidingly mounted adja cent to said piston and adapted to engage the yoke and piston to unseat the valves when the piston is moving in one direction, a spring mounted between the cup and piston and adapted to be compressed before the unseating of the valves by the cup, and to complete the movement of the valves, a rod attached to said yoke and extending through said cup and spring and into said tubular piston rod, said rod having a head on the end thereof lying within the hollow piston rod, and adapted when the piston is moving in the opposite direction to engage and compress said spring.

2. In a water motor, in combination, a cylinder having a head thereof, provided with inlet and outlet chambers, inlet and outlet valves mounted in said chambers, a yoke connecting said valves, a piston movable in said cylinder, a tubular rod extending through the axis of said piston to the exterior of the cylinder, a slidable rod telescoped in said tubular rod having one end enlarged and the other end connected to said yoke, a cup through which said slidable rod extends, said cup having a loose ccnnection with one of the exterior sides of the piston, and a conical spring arranged between the cup and the piston and through the coils of which said slidable rods extends, the enlarged end of said slidable rod being adapted to engage the spring to operate the valves in the movement of the piston in one direction, and the cup being adapted to engage the yoke to operate the valves in the movement of the piston in the other direction, substantially as specified.

3. In a water motor, a cylinder, a boss extending from one head of said cylinder, a nut on said boss, a base member, and pro jest-ions extending from said base member and lying between the nut and the cylinder head, said projections permitting the cylinder to be moved vertically and horizontally.
